Field data for the Vegetation Mapping Inventory Project of George Washington Carver National Monument
2011-2012. Field data for the Vegetation Mapping Inventory Project of George Washington Carver National Monument
This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. Vegetation data were collected at 16 plots by MoRAP staff in June of 2011. In the lab, the locations of plots were randomly placed within the following general strata based on field observation points and viewing of air photos and digital soils surveys: woodland and forest over moist soils, woodland and forest over better-drained soils, shrubland and open woodland, restored prairie, and non-native fescue grassland. Plots were located >30 m from an obvious land cover edge, and for each point there was at least one alternate, should the original point be determined unusable in the field (e.g. close to an un-mapped trail or road, stand too small). The stratified random plot location information was loaded into a GPS and workers navigated to the plot in the field for field sampling. Woodlands and forests were sampled with a 10 m x 40 m plot (400 sq m), shrublands and open woodlands with a 10 m x 20 m plot (200 sq m), and herbaceous vegetation with a 5 m x 20 m plot (100 sq m). Minimal flagging was used to mark the plot. Data were collected using a plot survey form. The survey form includes sections for plot location and description, as well as vegetation and environmental information about the plot. Vegetation sampling included information about structure and physiognomy, with leaf phenology, leaf type and physiognomic class recorded for the dominant vegetative stratum. Restored tallgrass prairie covers 134 acres (54.1 ha), or 57% of the park. An additional 54 acres (21.7 ha), or 23% of GWCA, is in ruderal woodland and forest.
